Actual conversation from this morning:
Nico: Is the South Pole in the middle of Antarctica?
me: Yes, it is.
Nico: Is the South Pole the only part of Antarctica where there's penguins?
me: Actually, the penguins don't live at the South Pole because it's too far away from the ocean. They live more around the edges, by the sea [indicating on the map Nico has drawn of Antarctica].
Nico: So who lives at the South Pole?
me: Nobody lives at the South Pole.
Nico: So why does the South Pole exist then?
me: Oh, I dunno. No reason, I guess...
